'Mosaic' in the Bible

But the Pharisees and the lawyers [who were experts in the Mosaic Law] annulled and set aside God’s purpose for themselves, not having been baptized by John.

One of the lawyers [an expert in the Mosaic Law] answered Him, “Teacher, by saying this, You insult us too!”

Woe to you lawyers, because you have taken away the key to knowledge (scriptural truth). You yourselves did not enter, and you held back those who were entering [by your flawed interpretation of God’s word and your man-made tradition].”
